How to install Windows or any OS on a Dedicated Server via iDARC/IPMI/KVM

Installing an operating system (OS) on a dedicated server is a critical task for setting up a robust hosting environment. Using remote management tools like iDRAC (Integrated Dell Remote Access Controller), IPMI (Intelligent Platform Management Interface), or KVM (Keyboard, Video, Mouse) over IP makes this process efficient, especially when managing servers remotely. These tools allow you to interact with your server as if you were physically present, enabling OS installation without needing direct access to the hardware. In this blog post, we’ll guide you through the steps to install Windows or any other OS on a dedicated server using iDRAC, IPMI, or KVM, ensuring a smooth and successful setup.

What are iDRAC, IPMI, and KVM?

Before diving into the installation process, let’s briefly explore these tools:

• iDRAC: A Dell-specific remote management interface that provides access to server hardware, including virtual media, console access, and system monitoring.
• IPMI: A set of computer interface specifications for an autonomous computer subsystem that provides management and monitoring capabilities independently of the host system’s CPU, firmware (BIOS or UEFI), or operating system.
• KVM over IP: A hardware-based solution that allows remote access to a server’s keyboard, video, and mouse, simulating a physical connection over a network.

These tools provide a virtual console and media capabilities, allowing you to boot from an ISO file and install an OS remotely. This guide assumes you have access to one of these interfaces and the necessary credentials.

Prerequisites for OS Installation

To install an OS on your dedicated server, ensure you have the following:

1. Access to iDRAC/IPMI/KVM: Obtain login credentials (IP address, username, and password) from your hosting provider.
2. OS Installation Media: Download the ISO file for the desired OS (e.g., Windows Server, Ubuntu, CentOS, etc.) from the official website.
3. Stable Internet Connection: A reliable connection is essential for remote access and downloading large ISO files.
4. Compatible Browser or Software: Some interfaces require specific software (e.g., Java or HTML5-based consoles) or compatible browsers.
5. Server Specifications: Verify that your server meets the OS’s hardware requirements (e.g., CPU, RAM, storage).
6. Backup Plan: If the server already has data, back it up to avoid accidental data loss during installation.

Step-by-Step Guide to Installing an OS

The process for installing an OS using iDRAC, IPMI, or KVM is similar, with slight variations depending on the interface. Below is a comprehensive guide tailored to these tools.

Step 1: Access the Remote Management Interface

1. Log in to iDRAC/IPMI/KVM:
   • Open a web browser and enter the IP address provided by your hosting provider (e.g., https://192.168.1.100 for iDRAC or IPMI).
   • Log in using your credentials. For iDRAC, this is typically the root user or a custom admin account. For IPMI or KVM, check with your provider for specific credentials.
   • If prompted, install any required plugins (e.g., Java for older iDRAC versions) or ensure your browser supports HTML5 for newer interfaces.
2. Launch the Virtual Console:
   • In iDRAC, navigate to the “Virtual Console” or “Console” tab and click “Launch.”
   • For IPMI, look for a “Remote Console” or “KVM” option.
   • For KVM over IP, access the console through the provided interface or software (e.g., Supermicro IPMIView).
   • This opens a window simulating the server’s monitor, keyboard, and mouse.

Step 2: Mount the OS ISO File

1. Prepare the ISO File:
   • Download the ISO file for your chosen OS (e.g., Windows Server 2022, Ubuntu 22.04, or CentOS Stream) and store it on your local computer or a network-accessible location.
   • Ensure the ISO is not corrupted by verifying its checksum (e.g., MD5 or SHA256) against the official source.
2. Mount the ISO as Virtual Media:
   • In iDRAC:
     • Go to the “Virtual Media” section and select “Connect Virtual Media.”
     • Choose “Map CD/DVD” or “Virtual CD/DVD/ISO” and browse to the ISO file on your local machine.
     • Click “Map Device” to mount the ISO.
   • In IPMI:
     • Navigate to the “Virtual Media” or “Remote Media” tab.
     • Select the option to mount an ISO and upload or link to the ISO file.
   • In KVM over IP:
     • Use the KVM interface to attach the ISO as a virtual CD/DVD drive.
     • Some KVM solutions require uploading the ISO to the server’s storage or a network share.
3. Verify the Mount:
   • Ensure the virtual media is recognized by the server. You may need to refresh the virtual console or check the server’s boot menu.

Step 3: Configure the Server to Boot from the ISO

1. Access the BIOS/UEFI Settings:
   • Restart the server via the iDRAC/IPMI/KVM interface (look for “Power” or “Reset” options).
   • As the server reboots, enter the BIOS/UEFI setup by pressing the appropriate key (e.g., F2 for Dell servers, Del for others). The key is usually displayed in the virtual console during boot.
   • Alternatively, use iDRAC’s “Boot” menu to set the boot order without entering the BIOS.
2. Set the Boot Order:
   • In the BIOS/UEFI, navigate to the “Boot” or “Boot Order” section.
   • Set the virtual CD/DVD drive (where the ISO is mounted) as the first boot device.
   • Save changes (usually F10) and exit, causing the server to reboot.
3. Boot from the ISO:
   • The server should now boot from the mounted ISO, launching the OS installation wizard in the virtual console.

Step 4: Install the Operating System

The installation process varies depending on the OS, but the general steps are similar:

1. Follow the OS Installation Wizard:
   • For Windows:
     • Select your language, time zone, and keyboard layout.
     • Click “Install Now” and enter the product key (if required).
     • Choose the edition (e.g., Windows Server 2022 Standard) and accept the license terms.
     • Select “Custom: Install Windows only” and choose the target drive/partition.
     • Follow the prompts to complete the installation.
   • For Linux (e.g., Ubuntu, CentOS):
     • Select the installation language and keyboard layout.
     • Configure network settings (if prompted) or proceed with default settings.
     • Partition the disk (use “Guided” partitioning for simplicity or manual for custom setups).
     • Install the base system and configure user accounts as prompted.
2. Monitor the Installation:
   • The installation may take several minutes, depending on the OS and server hardware.
   • Keep the virtual console open to respond to any prompts (e.g., reboot requests).
3. Eject the Virtual Media:
   • Once the installation is complete, the server may reboot automatically.
   • Unmount the ISO file via the iDRAC/IPMI/KVM interface to prevent the server from booting into the installer again.
   • If needed, return to the BIOS/UEFI and set the hard drive as the first boot device.

Step 5: Post-Installation Configuration

1. Verify the OS Boot:
   • After rebooting, the server should boot into the newly installed OS, visible in the virtual console.
   • Log in using the credentials set during installation (for Linux) or the default administrator account (for Windows).
2. Install Drivers and Updates:
   • For Windows, download and install server-specific drivers (e.g., network, storage) from the manufacturer’s website (e.g., Dell’s support page for iDRAC-enabled servers).
